Angularjs的ng-animate + css过渡滑动效果

Question

我正在尝试用Angular的新ng-animate特性实现滑动效果。我从演示站点中获取了一些代码，并准备了一个小提琴。

问题是，当项目从数组中交换时，滑动DIV以下的元素不断上下移动。我试过用line-height，但没有成功。

是否有可能修复上述行为?或者有更好的方法只用angular和CSS来实现它吗?

Answer 1

您可以将输入和按钮包装在div中，并将其置于绝对位置。

这里是一个演示

HTML

<div ng-app="">    
<div ng-controller='anim' >
    <div ng-repeat="item in lst"  ng-animate=" 'wave' ">
    {{item}}
    </div>
    <div class="wrapperInput">
        <input ng-model="cmt"> 
    <button ng-click="clk()"> Slide </button>
        </div>
    </div>  
</div>

CSS

  </style> <!-- Ugly Hack due to jsFiddle issue: http://goo.gl/BUfGZ --> 
<script src="http://code.angularjs.org/1.1.4/angular.min.js"></script>
<style>
/**/
.wrapperInput{position:absolute;top:30px;}
/**/
.wave-enter-setup, .wave-leave-setup {
  -webkit-transition:all cubic-bezier(0.250, 0.460, 0.450, 0.940) .5s;
  -moz-transition:all cubic-bezier(0.250, 0.460, 0.450, 0.940) 0.5s;
  -o-transition:all cubic-bezier(0.250, 0.460, 0.450, 0.940) 0.5s;
  transition:all cubic-bezier(0.250, 0.460, 0.450, 0.940) .5s;
    line-height:100%;
}
.wave-enter-setup {
  position:relative;
  left:100%;
 line-height:100%;
}

.wave-enter-start {
  left:0;
line-height:100%;
}
.wave-leave-setup {
  position:absolute;
  left:0;
line-height: 100%;
}
.wave-leave-start {
  left:-100%;
  line-height: 10%;
}

JS

function anim($scope,$timeout){
    $scope.lst = [];
    $scope.master = ['[1] John who is 25 years old.','[2] Jessie who is 30 years old.','[3] Johanna who is 28 years old.','[4] Joy who is 15 years old.','[5] Mary who is 28 years old.','[6] Peter who is 95 years old.','[7] Sebastian who is 50 years old.','[8] Erika who is 27 years old.','[9] Patrick who is 40 years old.','[10] Samantha who is 60 years old.'];
$scope.lst.unshift($scope.master[Math.floor((Math.random()*10)+1)]);
    $scope.clk = function() { clik();}
    function clik() {
    //alert('here');
         $scope.lst.unshift($scope.master[Math.floor((Math.random()*10)+1)]);         
         $scope.lst.pop();  
        $timeout(function(){ clik();},2000);
    }
    clik();
};

试试这个:

CSS:

.wave-enter-setup, .wave-leave-setup {
  -webkit-transition:all cubic-bezier(0.250, 0.460, 0.450, 0.940) .5s;
  -moz-transition:all cubic-bezier(0.250, 0.460, 0.450, 0.940) 0.5s;
  -o-transition:all cubic-bezier(0.250, 0.460, 0.450, 0.940) 0.5s;
  transition:all cubic-bezier(0.250, 0.460, 0.450, 0.940) .5s;
  position:relative;
  display:table;
  float:left;
}
.wave-enter-setup {
  left:100%;
}
.wave-enter-start {
  left:0;
}
.wave-leave-setup {  
  left:0%;
}
.wave-leave-setup.wave-leave-start {
  left:-100%;
}
.floatNone{ clear:both; position:relative;}

HTML:

<div ng-app="">    
    <div ng-controller='anim' >
        <div ng-repeat="item in lst"  ng-animate=" 'wave' " >{{item}}</div>
        <div class="floatNone">
            <input ng-model="cmt" >     
            <button ng-click="clk()"> Slide </button>
        </div> 
     </div>    
</div>
